Feature: Parse partial uncertain or approximate dates
  As a Ruby programmer
  I want to convert Date/Time objects to EDTF strings

  @201 @level2
  Scenario Outline: Prints uncertain or approximate dates
    When I parse the string "<string>"
    Then the year should be uncertain? "<?-year>"
    And the month should be uncertain? "<?-month>"
    And the day should be uncertain? "<?-day>"
    And the year should be approximate? "<~-year>"
    And the month should be approximate? "<~-month>"
    And the day should be approximate? "<~-day>"

    Scenarios: Uncertain or approximate dates, day precision
